To all whom t may concern: y' v Be it known thatlLJosEPi-rll TREGONING, a citizen of the Y United States, residing at Greeley, in the county ofWeld vand State of l Colorado, have inventedcertain new andjuse--' ful Improvements in Leaf-Spring-Lubrlcat'i:

ing Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a leaf-spring lu# bricating tool.

The object of the present invention is to provide a simple, practical and efl'icient lubricating tool of strong, durable and comparatively inexpensive construction adapted to be readily applied to upper and lower leaf-springs of automobiles and various other vehicles and capable of easy operation tospread the leaves suiiiciently to introduce a lubricant between thesame to the desired extent.

A further object of the invention is to provide a leaf-spring lubricating tool of this character equipped witlica gravity feed for lubricating the leaves of the upper springs when the device is in an upright position, and provided also with a force speed for forcing oil or other lubricant between the leaves of a lower spring when the toolis inverted.

Vith these and other objects in view,'the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

*tool oeinprisesiiir itslc'onstruction two members feacli' consisting of l`a vplate on body-1 provided@ at@ tlie vlowerf vend with an# inwardly projecting tapered spring-engaging portion portion or arm 3, the top portions or arms 3 of the two members being provided with eyes 4L and hinged together by a pintle 5, preferably consisting of a bolt, as clearly shown in Fig. 2 of the drawing. The spring- `engaging portions 2 are adapted to engage a spring at opposite sides thereof, and to be forced between the leaves of the spring for separating or spreading. the leaves to enable a lubricant to be introduced in the said leaves. The sides or members of the tool are connected by an adjusting screw 6 piercing the plate 1 and provided at one end with a head 7 and having a nut S equipped with a handle 9 to enable it to be readily rotated forforcing the sides or members together.

Each side or member is provided with a pair of lubricating passages 10 and 11 extending from the top of the plate or body 1 to the lower end thereof and having angularly disposed portions 12 and 13 which eX- tend along the engaging portions 2 of the sides or members to the transverse edges thereof so as to feed the oil or other lubricant between the leaves of the spring. The passage 10 extends Ifrom the top of the side or member and is open at the upper end to enable an oil can or other lubricant recep-` tacle to supply the passage with oil for lubricating the leaves of a spring when the tool is operating in an upright position. The other lubricant passage 11 is provided with an enlarged or counterbored upper portion 14e forming a chamber and threaded to receive a threaded screw or plunger 15 adapted, when the tool is inverted, for. operating on a lower spring, to forcefthe oil or other lubricant out through the passage 11 into the spring. The threaded plunger or screw 15 is provided with a suitable operating handle 16.

'The tool is operated by placing the engaging portions 2 on opposite sides of a spring and then rotating the nut 8 by the handle 9 until thesaid engagingportions 2 are forced between and spread the leaves of the spring. The lubricant is then supplied to the spring an 11 of each of the sides or members. The threaded plunger or screw, by closing the chamber 14 at the top thereof and excluding the pressure of the atmosphere therefrom will prevent the leaking of the lubricant from the passage 11. f What is claimed is: A s Y A leaf-spring lubricating tool including two sides or members hinged together at the topv and provided at the bOttO1n"With inwardly extending tapered spring engaging portions adaptedto spread the leaves, said sides or members being bothproyided `With lubricant passages arranged in pairs, -one member of each pair being enlarged to form a chamber, plungers Operating in the chainbers for forcing lubricant through the passages leadingV therefrom When the device is inyerted, and means for adjustably connecting the sides or members.
